US Immigrant applying to medical in EU?

Okay so I am an immigrant in the US and currently a junior in HS. I want to do medicine and don't know if it's better to pick US or EU. I have read that's it's much cheaper to study and stay in EU compared to US, but I am also wondering about like if I wanted to move back to the US from EU how that process would work. And if i dis not move back what is the medical situation in EU like how is the pay and the work like balance. like is it worth it doing all of that? Has anyone done this and if you have please give me some advice, I am super stressed out. Also if there's any advice on majors in general that's much appreciated I don't feel completely set in a path yet <3
